Frequently Asked Questions

Can I use the HLG-120H-C1050B with a building automation system to dim LED fixtures?

Yes. The HLG-120H-C1050B has a 1-10V/PWM dimming input, making it compatible with building management systems that output standard dimming signals. It delivers 1050mA constant current at up to 155.4W, suitable for automating light levels in commercial spaces based on occupancy or daylight schedules.

Is the HLG-120H-C1050B suitable for dimmable LED track lighting in a gallery or showroom?

Yes, provided the track light modules operate at 1050mA with a combined forward voltage between 74V and 148V. The dimming input allows precise brightness control for accent lighting, which is essential in galleries where light levels affect artwork display. The constant current output ensures uniform brightness across all modules.

Can the HLG-120H-C1050B power LED arrays in outdoor architectural lighting with dimming?

Yes. With IP65 water resistance and a -40°C to +90°C operating range, the HLG-120H-C1050B can drive outdoor architectural LED fixtures while providing dimming control. It handles 155.4W at 1050mA constant current, suitable for facade lighting, wall washers, or landscape uplights that require brightness adjustment.

What is the CC voltage range of the HLG-120H-C1050B and why does it matter?

The CC voltage range is 74-148V. This means the driver automatically adjusts its output voltage within this window to maintain a steady 1050mA through the LED load. If your LED string's forward voltage falls outside this range, the driver cannot regulate properly. Always ensure your total LED forward voltage sits between 74V and 148V.

How does the HLG-120H-C1050B differ from the C1050A and C1050AB versions?

All three deliver 155.4W at 1050mA with a 74-148V CC range and IP65 rating. The C1050B (this model) includes a 1-10V/PWM dimming input but no output adjustment potentiometer. The C1050A has the adjustable potentiometer but no dimming input. The C1050AB combines both adjustment and dimming in one unit.

Can the HLG-120H-C1050B be mounted in a damp indoor environment like a swimming pool area?

The IP65 rating protects against dust and low-pressure water jets, which is generally adequate for damp indoor environments such as pool halls or natatoriums where splashing may occur. However, it is not rated for submersion, so it should be mounted above any potential water line and away from direct spray from pool fixtures.
